IIVIPROVED METHOD OF SINKING WELL-TUBING.

Specification forming part of Letters Patent No. 52,792, dated February20, 1866.

To all whom it may concern:

Be it known that I, R. F. OsGooD, of Rochester, in the county ot' Monroeand State of New York, haveinvented a new and Improved Method of SinkingWell-Tubing; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, making part of this specification.

Figure 1 is a sectional elevation of my improved tubing with the wrenchor key in place for turning the interior cylinder or section; Fig. 2, across-section in the plane of line :v x, Fig. l; Fig. 3, a perspectiveview of the interior cylinder or section, with a portion broken away toshow the valve therein; Fig. 4, a perspective view of the lower end ofthe wrench or key.

Like letters of reterenceindicate corresponding parts in all thefigures.

My improvement belongs to that class where tubing is driven into theearth in order to avoid the labor and expense of digging a well.

The invention consists, essentially, in the employment of a shortcylinder or section of tube inside the main tubing at the bottom, soarranged that in the act of driving the ports in the sides of the maintubing may be closed to exclude dirt, but when driven in place thecylinder or section may be turned partially around, so as to bring itsports in coincidence with those of the tubing for the admission ofwater.

It also consists in the employment of wirecloth covering the ports ofthe cylinder or section for the purpose of straining the Water andexcluding foreign matters, and in the use of a valve in the cylinder orsection for sustaining of the column of water, Src.

As represented in the drawings, A is the ordinary tubing, which isdriven into the earth by entering a hole or passage previously made by along rod or drill. At its bottom are made ports a a, or equivalentperforations, on opposite sides, as clearly indicated in Figs. 1 and 2.To the lower extremity of the tubing is rigidly secured a point, l,which may be of the form shown or any other desired.

In the lower end ot' the tubing is situated a short cylinder or sectionof tube, B, fitting closely therein, but yet capable of being readilyturned. This cylinder has also ports or pert'orations c c on oppositesides, corresponding in position with those in the tubing. I cover theseports on the inside with wire-cloth d of fine texture, so as tothoroughly strain and filter the water that enters and prevent thepassage of any extraneous bodies.

At a suitable distance above the portsv I also prefer to provide thecylinder or section with a valve, f, of any ordinary construction, Fig.3. The top of the cylinder is provided with notches g g, or equivalent,in which catches a wrench or key, C, whose handle extends to the top ofthe well, by which means the cylinder is turned at any time.

In the act of driving down the cylinder rests in the tubing in theposition indicated in Figs. 1 and Z-that is, with the closed sides ofthe cylinder opposite the ports or perforations of the tubing. This isfor the purpose of preventing the pressure against the sides of thetubing in driving from forcing the dirt inward and filling the tubing,as is the case especially in quicksands', where no preventive isemployed; but when fully driven down the wrench or key C is lowered tillit engages with the top of the cylinder, when the latter is turnedaround sufficiently to bring the ports or peri'orations c c incoincidence, when the water enters and is raised by means of a pumpattached to the top of the tubing. The

cylinder holds in the desired position usually by its friction and bythe sediment that collects between it and the tubing, which latter yalso packs it.

A device is already known in which the opening-point is attached to ahollow shank that rests loosely in the tubing. When the whole is drivenin place the main tubing is raised so as to expose the hollow shank,which has perforations to admit water.

There are several objections to this arrangement. The main tubing mustbe raised to admit water, which, owing to the weight and friction, is aconsiderable labor. The weight of the tubing itself, the action offrost, and many local causes have a tendency to lower the tubing on theshank so as to make its working uncertain.

It will be seen that I obviate these difticulties, for the cylinder orsection B has simply to be turned around a little distance, requiring noexertion at all, and when once in place it is not .liable to becomedisplaced under ordinary circumstances. for the motion of the Water isnot great and the sediment that collects soon fixes itin place. If',however, any difficulty should be experienced from displacement, a smallspring can be easily attached to the cylinder, which, pressing againstthe sides of the tubing, would surely hold it.

The wire-cloth d is of especial use in quicksands, where the pressurearound the main tubing is constant and unvarying. Much dif- Iiculty isexperienced in ordinary devices from the quicksand, which constantlypresses inward through the ports, and frequently to such a degree as toobstruct the tube and render the Whole arrangement useless. the portswith fine Wire-cloth or equivalent perforated material all difficulty ofthis kind is obviated. This covering is also of great benefit inordinary soils, for it excludes small stones and all extraneous matter,and besides this makes the water much purer by straining.

By theuse of lthe valve fin the cylinder itenables me to support thecolumn of water from By covering the bottom, and if IY desire to so do Ican-then employ the cylinder or section B as a piston. This is ofespecial importance Where the Well is ot'such depth that a lift insteadot' a suction pump is necessary.

What I claim as my invention, and desire Bi. F. OSGOOD.
